Question

Joe's father will be twice his age 6 years from now. his mother was twice his age two years before. if joe will be 24 two years from now, what's the difference between his father's and mother's ages?

Answer 1

Joe's present age = 22
Because Joe will be 24, 2 years from now.

6 years from now, Joe's age = 28
Joe's father's age = 2*28 = 56 years
Father's present age = 56 - 6 = 50 years....(i)

2 years ago, Joe's age = 20
Joe's mother's age = 2*joe's age = 40 years
Mother's present age = 40+2 = 42 years...(ii)
Difference between father's and mother's age = 50 - 42 = 8 years..[eq(i) & eq(ii)]
Hope it helps.
